Not sure that’s true or not. All I know is that he was not the Zeke we were use to last year I expect him to be the Zeke we’re use to after the work he’s put in this offseason.

So, based on looking at the above stats what one can surmise is that Zeke has declined as a runner partially due to the Dallas shift in philosophy to a more pass heavy football team (look at Zeke's catches dramatically increase while his rushing attempts per game has decreased) but also due in part to the fact that Zeke is no longer that homerun hitting running back who can be relied upon to carry an offense as he was in his rookie season.
